Answer:

y=-1/2x+2

Step-by-step explanation:

y = mx + p

m=slope = -1/2

p= y-intercept = 2

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 2

Step-by-step explanation:

The segment for - 2 ≤ x ≤ 2 is a straight line

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (2, 1) ← the endpoints of the line

m = [tex]\frac{1-3}{2+2}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]

Note the line crosses the y- axis at (0, 2) ⇒ c = 2

y = - [tex]\frac{1}{2}[/tex] x + 2 ← equation for - 2 ≤ x ≤ 2

The question involves converting the model depth from centimeters to meters, which typically requires dividing by 100. However, without a specific scale or additional detail, the direct conversion of 32cm would be 0.32 meters.

The student's question is about converting the depth of a model water tower, provided in centimeters, to its actual depth in meters without giving a specific depth in the question. This concept usually involves understanding the scale of models and how to apply proportional reasoning to determine actual sizes. However, without a specific scale or the actual depth given in the question, we can't calculate the actual depth.

Generally, to convert from centimeters to meters directly, we divide the length in centimeters by 100, because 1 meter equals 100 centimeters. For example, if a model tower's depth is 32cm, to find this depth in meters, you would divide 32 by 100, which equals 0.32 meters.

Answer:

-5x³ -5x² -9x - 4

Step-by-step explanation:

(-6x³-4x²-8)+(x³-x²-9x+4)

Add the like terms.

-6x³ and x³ are like terms. -6x³ + x³ = -5x³

-4x² and -x² are like terms. -4x² - x² = -5x²

-8 and 4 are like terms. -8 + 4 = -4

-6x³-4x²-8 +x³-x²-9x+4 = -5x³ -5x² -9x - 4

Answer:

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for A

A = 180° - (90 + 48)° = 180° - 138° = 42°

----------------------------------------------------------

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{18}{a}[/tex]

Multiply both sides by a

a × tan48° = 18 ( divide both sides by tan48° )

a = [tex]\frac{18}{tan48}[/tex] ≈ 16.2 ( to the nearest tenth )

-----------------------------------------------------------

sin48° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{18}{c}[/tex]

Multiply both sides by c

c × sin48° = 18 ( divide both sides by sin48° )

c = [tex]\frac{18}{sin48}[/tex] ≈ 24.2 ( to the nearest tenth )

Step-by-step explanation:

its a parabola that opens upward, the zeros are x=4 and x=3

The solution is [tex](1,1)[/tex]

Step-by-step explanation:

The system of linear equation is

[tex]y=-3x+4[/tex] and [tex]y+\frac{1}{3} y=\frac{4}{3}[/tex]

Using substitution method, let us substitute [tex]y=-3x+4[/tex] in the equation

[tex]y+\frac{1}{3} y=\frac{4}{3}[/tex]

[tex]-3 x+4+\frac{1}{3}(-3 x+4)=\frac{4}{3}[/tex]

Multiplying the term [tex]-3x+4[/tex] by [tex]\frac{1}{3}[/tex], we get,

[tex]-3 x+4-x+\frac{4}{3}=\frac{4}{3}[/tex]

Subtracting both sides by [tex]\frac{4}{3}[/tex],

[tex]-3x+4-x=0[/tex]

Simplifying, we get,

[tex]\begin{aligned}-4 x+4 &=0 \\-4 x &=-4 \\x &=1\end{aligned}[/tex]

Now, substitute [tex]x=1[/tex] in [tex]y=-3x+4[/tex]

[tex]y=-3(1)+4\\y=-3+4\\y=1[/tex]

Thus, the solution is [tex](1,1)[/tex]

Answer:

y = -3x + 4

x + 1/3y = 4/3

Substitute the first expression into the second equation for y:

x + 1/3(-3x + 4) = 4/3

x - x + 4/3 = 4/3

4/3 = 4/3

Thus, all real numbers are solutions.

Answer:

Step-by-step explanation:

Total cost  = 1.9* 40 = 76.0 = $76

When unit rate is given,multiply.

The total cost of 1.9 cubic meters of soil is $76. This is calculated by multiplying the amount of soil bought (1.9 cubic meters) by the cost of one cubic meter of soil ($40).

To calculate the total cost, we have to multiply the amount of soil bought (in cubic meter) by the cost of one cubic meter of soil. Here, the student is buying 1.9 cubic meters of soil and the cost of one cubic meter of soil is $40.

So, Total cost = amount of soil * cost of one cubic meter of soil
= 1.9 * 40
= $76

Therefore, the total cost of 1.9 cubic meter of soil is "$76."

Answer:

x = 6

Step-by-step explanation:

Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is

[tex]\frac{3}{x-4}[/tex] = [tex]\frac{x}{4}[/tex] ( cross-  multiply )

x(x - 4) = 12 ← distribute left side

x² - 4x = 12 ( subtract 12 from both sides )

x² - 4x - 12 = 0 ← in standard form

(x - 6)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 2 = 0 ⇒ x = - 2

However, x > 0 , thus x = 6

Answer:

  (8π -8√3) cm²

Step-by-step explanation:

The area of a circle with radius 4 cm is given by ...

  A = πr² = π(4 cm)² = 16π cm².

The red shaded portion is part of a semicircle. That semicircle will have an area half that of the circle, so ...

  A/2 = 8π cm²

__

The triangle OCB is an equilateral triangle, so the angle at B is 60°. The side AC is then √3 times side BC*, so is 4√3 cm. The area of triangle ABC is then ...

  A = (1/2)AC·BC = (1/2)(4√3 cm)(4 cm) = 8√3 cm²

This area is subtracted from that of the semicircle to obtain the red shaded area:

  red area = semicircle area - triangle area

  red area = (8π -8√3) cm²

____

* AC can be found either from the Pythagorean theorem (√(8²-4²)), using trig functions (4tan(60°)), or using your knowledge of 30°-60°-90° triangles.

By setting up a system of equations from the given scenarios, we find that the cost of a burrito platter is $32 and the cost of a taco platter is $26.

To solve Carmen's problem about the cost of burrito and taco platters, we need to set up a system of equations based on the information given.

We know she spent $58 on one burrito platter and one taco platter and $90 on two burrito platters and one taco platter.

Let's denote the cost of a burrito platter as B and the cost of a taco platter as T.

Step 1: Establish the Equations

The first scenario gives us the equation: B + T = 58.
The second scenario gives us the equation: 2B + T = 90.

Step 2: Solve the Equations

From the first equation, we can express T in terms of B: T = 58 - B.

Therefore, the cost of a burrito platter is $32 and the cost of a taco platter is $26.

Answer: [tex]\angle GFH[/tex]

Step-by-step explanation:

A Transversal is defined as a line that intersect two or more lines.

For this exercise it is important to know that when a Transversal cut two parallel lines, several angles are formed. These are grouped in pairs.

One of those pairs are called "Alternate exterior angles".

Alternate exterior angles are those non-adjacent angles that are located outside the parallel lines and on opposite sides of the Transversal.

Alternate exterior angles are congruent, which means that they have equal measure.

In this case you know that the Transversal [tex]CH[/tex] cuts the parallel lines [tex]AD[/tex] and [tex]EG[/tex].

Therefore, based on the explanation given before, you can identify in the picture given in the exercise that the angles [tex]\angle ABC[/tex] and [tex]\angle GFH[/tex] are Alternate exterior angles.

Answer:

The equation of the required straight line is y = 4x + 1.

Step-by-step explanation:

The equation of all the straight lines that are parallel to the straight line y = 4x - 3 is given by  

y = 4x + c .............. (1)  

where, c is any real constant and c ≠ - 3.

{Since parallel straight lines have the same slope and different y-intercept }

Now, we have to find the value of c such that the parallel straight line passes through the point (-1,-3).

Now, putting x = - 1 and y = - 3 in equation (1) we get,

- 3 = 4(- 1) + c

⇒ c = 1

Therefore, the equation of the required straight line is y = 4x + 1. (Answer)

Answer:

x intercept is 15 and y intercept is -3.75

Step-by-step explanation:

The first thing is to form equation with the given tow point using the formula

y-y1/x - x1 = y2 - y1/ x2 - x1

y + 5/x + 5 = -2 + 5/7 + 5

y + 5/x + 5 = 3/ 12

3x + 15 = 12y + 60

12y - 3x = -45

On x intercept y = 0

x = 15

On y intercept x = 0

y = -3.75

Answer:

[tex]y=4000*(1.05)^t[/tex]

Step-by-step explanation:

The graduating class grows by 5% each year, this means after 1 year the number of students graduating will be 105% of 4000, or

[tex]4000*\frac{105}{100} =4000*1.05[/tex]

And after 2 years it will be

[tex](4000*1.05)*1.05[/tex]

and so on. Thus, after [tex]t[/tex] years the number of students [tex]y[/tex] will be

[tex]\boxed{ y=400*(1.05)^t}[/tex]

An exponential function to model the number of students y in the graduating class t years  after 2008 is y = 4000(1.05)^t

The standard exponential function is expressed as:

y = ab^x

If a college with a graduating class of 4000 students in the year 2008 predicts that its graduating class  will grow 5% per year, hence the required exponential equation will be:

y = 4000(1.05)^t
